is simple and compact in structure, and'onein which the parts are simple and economical to produce and easily assembled.

Further objects, and objects relating to structural details, will ,definitely appear from the detailed description to follow.

I accomplish the objects .of my invention by the devices and means described in thefollowing specification.

The structure described constitutes oneetfective embodiment of my invention. (thercmbodiments would be readily devised by those skilled in the art.V

The invention is clearly defined and .pointed out in the claim.

A structure constituting an effective and preferred embodiment of the features of my invention is clearly illustrated in the accempanil ing drawing, forming a part of this specification, in which:

Figure 1 is a plan View of a structure embodying the features of my invention, the joint being shown-in connection with two shaft sections; Fig. 2 is a longitudinal section taken on a line corresponding to line 2 of Fig. 1, certain parts being shown in full liuc to better illustrate their form'Fig. 3 is a transversesection taken ona line corresponding to line 3--3 of Fig. '1, the journal pins being shown mainly in full lines; Fig. V11- is a perspective View .of the journal block with the journal pins arranged therein.

Vmembers 2 are adapted to receive the shaft sections, the shaft sections of. the structure illustrated being secured in the shaft members by mea-ns of thepins These pins are retained by' lxnetnsf of tl'1e screws 4, which position.

threaded` into the ends of, the Tieftmembers transversely t9 the pins, see gl 2i" The journal block 5 is prlo'vided'w'ltii 'tr -nsversely disposed holes (ifa-nd 7 ,-the holes ingof unequal diameters. Throu h. the larger hole (i, I arrange the shouldere journal pin S. This journaljpin 8 is pnoaiidedl with a central. hole adapted to receive the journal p in 9 whiehis arranged ,through thejother hole in the -journal block, and through the pin S, the pin 9 thus serving as a locking piu for the pin 8. 4

4The shaft members are provided with holes for the journal 'pins, the holes in the shaft members being of suflicient diameter to receive their respective journal pins. The shouldered journal pin is provided with bushings 10, which are threaded into its .shaft member, as clearly appears from the drawing. These bushings are shouldered at their outer ends forming enlarged heads.

The heads are countersunk and seated into the joint or shaft members.V The inner ends of these bushings arc preferably adapted to engage both the journal block and the shoulders of thc pin `8, so that lthe parts may be properly centered through the bush- In s. glhe bushings 10 are locked in position by means of the screws 11, which are threaded into the shaft member to en age the peripheries of the bushings, see fig. 2. The outer ends of these bushings and the ends. of-the journal pins are preferably fiush with the outer surfaces ofthe shaft members.

The journal pin 9 is retained or locked 4in position by means of the screw 12, which is threaded into one of the arms of its shaft transversely to .the piu., see Figs. 1 and 3.

The parts are thus all effectively locked in At the same time, they can be readily assembled and. disassembled. My improved universal joint is very simple and `compact in structure, and'the parts are simple and economical to produce and readily assembled. l Y

Having thus desc-tibed my invention, what I claim as new and desire to secure by Letters Patentlis:

In a universal joint, the combination of the bifurcated joint members; a joint block having pin holes of unequal diameter therethrough disposedvtransversely to each other; a pin with shouldered journals at lts ends'.

ings for said shouldered journals threaded into the arms of the corresponding joint member, the .said bushings being shouldered at their outer ends .forming an enlarged head on each bushing, said head being counter-sunk and seated substantially flush with the surface of said joint member, the ilmer ends of said bearing bushings being adapted to bear against the shoulders' of said 'journal pin and saidbloek; Vlocking screws for said bushings projeting into the outer'faee of said joint member and engaging the enlarged head end thereoend being Hush wlth the faces of the bushings; a smaller journal pin for the other joint member disposed and journaled through the smaller WILLIAM R.
